The GIQ-B series perfect vacuum air operated reed valve is with the compressed air is a power, through the pneumatics change air course direction, the control execution
air cylinder actuates the reed valve, puts through or shuts off in the vacuum pipeline the air current. Suitable actuating medium for air and non- caustic gas.
Neoma vacuum angle and inline valves are devices that regulate the flow of gases, fluids or materials through a structure or aperture by opening, closing or obstructing a portor passageway. Angle valve assembly consist of an actuator, a poppet and a valve body. The actuator provides the power to position or transport the valve's poppet which is attached to thevalve's body via a circular bonnet flange. The poppet closes or opens one of the valve's body ports. The valve body is a vacuum tight chamber that is crewed, flanged or weldedinto a larger vacuum vessel or system.

Crispin air and vacuum valves are designed to vent large quantities of air when filling pipelines, and to allow air to re-enter pipelines during drainage to prevent vacuum collapse. Sizes 1/2 thru 24 available, with a wide variety of materials and coatings available.
The vacuum valve is a protection device mounted on a nozzle opening on the top of a fixed roof atmospheric storage tank. Its primary purpose is to protect the tank against rupturing or imploding. Without an opening or a controlled opening, a fixed roof atmospheric tank would rupture under increasing pressure caused by pumping liquid into the tank or as a result of vapor pressure changes caused by severe thermal changes. Imploding, or the collapsing of a tank, occurs during the pumping out procedure or thermal changes.
